Plotting format 1d 10:05 in gnuplot

Question

How i able to plot this in gnuplot the following times in gnuplot?

But the graph does not seem to adapt the hours after the days.

set timefmt "%jd %H:%M"

in my test.csv there is:

0,1d 10:15
1,1d 10:05
2,1d 1:50
3,2d 3:30

plot "test.csv"

As seen in the picture the time is not plotted correctly.

Answer 1

You have to tell gnuplot that your data separator is comma. Per default it is whitespace. In the example below skip the $Data datablock and in the plot command replace $Data by Test.csv. There, column2 is plotted versus column1. Maybe you want it the other way round, it's not clear from your question, graph and plot command.

Code:

### plotting time data
reset session

$Data <<EOD
0,1d 10:15
1,1d 10:05
2,1d 1:50
3,2d 3:30
EOD

set datafile separator comma
myTimeFmt = "%jd %H:%M"
set format y myTimeFmt time

plot $Data u 1:(timecolumn(2,myTimeFmt)) w lp pt 7 notitle
### end of code

Result:
